Brazilian President Luiz Inácio Lula da Silva said Thursday that he will impose retaliatory tariffs on the United States if President Donald Trump follows through on a pledge to boost import taxes by 50% over the South American country's criminal trial against his predecessor, Jair Bolsonaro.

Lula said he will trigger Brazil's reciprocity law approved by Congress earlier this year if negotiations with the U.S. fail.

Just hours after hitting all-time highs, Wall Street was poised to open with losses on Friday, a possible sign that President Donald Trump's wave of tariff letters is again raising concern among investors.

The OPEC oil cartel said Thursday that demand for crude will continue to expand through at least 2050, calling efforts to rapidly shift away from fossil fuels an unworkable fantasy.

In its latest annual report on the outlook for oil demand, OPEC sees oil demand rising by 18.6 percent from 103.7 million barrels per day in 2024 to around 123 mbd in 2050. "There is no peak oil demand on the horizon," said Haitham Al Ghais.

"The United States has moved its deadline for finalizing deals with partner countries to the first of August. However, we aim to reach a deal before then, potentially even in the coming days, we have shown our readiness to reach an agreement in principle," EU trade spokesman Olof Gill said.
